My boyfriend is in the Navy and one of his uniforms I really love him in because he looks really good in it. They are his Navy Dress Blues.
My coworker was also in the Navy, he said that they have a nickname for the uniform I really like. The nickname is "13 chances to say no". (There are 13 buttons on the pants.)
I think they look good on guys, but I don't really have a fetish about uniforms or roleplaying with them. There's actually a firehall around the corner from me and when I'm going by, I will have a look if they're hanging around outside, but it's more about seeing a hot fit guy than about the uniform or the allure of a 'fireman' profession etc.
I gave the pizza delivery guy a hug because of his uniform
